Steam player data is incorrect

[therealsamf]

Currently we're using steam id's to list the number of players per game. We need to make an API request to correctly assess this

[therealsamf]

The API request for this is locked down in the browser because of CORS. So we're going to move this into the database and request the resources just like we do for the rest of our models' attributes

This should be ready to fix now that steam_players is in the database.
